Description

This dataset was generated for the publication: Christina Mooshammer, Benjamin Ackermann, Kai-Ernst Wilberg, Lilly Metten, Stephan Brons, José Vedelago, Christina Stengl, 2026. Influence of 3D printing parameters on radiological properties for PLA-based filaments in ion beam therapy. Submitted to Medical Physics. The attached Excel file "Material_parameter_and_physical_and_radiological_properties_of_FDM_materials.xlsx" contains two sheets, "SampleData" and "SlicerData". The first sheet "SampleData" contains detailed print settings as well as physical and radiological properties for a multitude of samples produced with nine different 3D printing fused deposition modeling (FDM) filaments based on polylactic acid (PLA). For each sample, 3D print parameters such as color, vendor, printing profile, printer, slicer, pattern, infill, extrusion factor, number of perimeters, number of top layers, number of bottom layers, bed temperature, extruder temperature, and volumetric speed are given. For physical properties, the weight of the sample, diameter and height measurements, as well as the density are listed with corresponding uncertainties (marked in orange). For radiological properties, stopping power ratio (SPR) relative to water and CT number were measured and are listed for each investigated sample with corresponding uncertainty. For the SPR measurements, the Rb(80)_sample of the displaced Bragg peak (BP) after passing through the sample and the reference Rb(80)_air recorded without the sample, the step size, with which the respective BP curve was recorded, and peak width (width of the BP curve at 80 % ionization) are listed (marked in blue). Additionally, the minimum, maximum, median, and mean CT contrast are listed in HU for a segmented region of interest (ROI) (marked in yellow). The standard deviation of this ROI was reported as the uncertainty. Lastly, the relative deviation from the CT calibration curve is listed for each sample (marked in gray). The second sheet "SlicerData" contains 3D print parameters and physical properties, as described above, for the samples produced for comparison between two slicer softwares, Prusa Slicer and Orca Slicer.
